Catapult like this https://www.youtube.com/watch?v=vrw1KplZm6c should work well - used on cars

Gears can be made by folding circle of paper, cutting knicks (like you do when making paper snowflakes) and using as template

Strip deconstructed corrugated cardboard round a circle of thick cardboard can work well if done correctly

Otherwise folded paper wedges (triangular prisms) and stick to outside of circles of thick cardboard glue together, but difficult unless bigger cogs

Do you know someone with laser cutter? STEMNET site might have some worksheets

Hi Everyone!
 
I’m stuck with coming up with a solution to 2 craft activities I’m using for family activities, has anyone seen or run something similar before and so can offer advice?
 
  1. Moving bus/car models
I have been making model buses out of small boxes (c.10cm tall), cardboard wheels, straws and dowels which roll along fine but I’d really like to make them self-propelling. I’ve tried balloon powered and elastic band powered but neither give enough power to propel the buses up a slight slope (we’re recreating a time a bus jumped over the opening bascules of Tower Bridge!). Does anyone have another way of propelling vehicles other than pushing them?!
 
  1. Cogs
I would like to do a cog making activity but have got stuck on how to make them, other than by using corrugated card wrapped around something circular. I’m looking for something that looks more like a cog than that!
 
Many thanks in advance
 
Sophie
